Whether this will result in greater numbers successfully overwintering as either eggs, larvae, pupae or adults remains to be seen.
And an early instar caterpillar was also found tucked away inside its nettle tent (see right). It will be interesting to see how this caterpillar develops through the winter.
Other reports in recent days of butterflies in farmers barns, houses and garden sheds suggest the cooling weather is now encouraging some species to move into sheltered places in preparation to over winter.The Bloxworth Snout is a regular over wintering moth in our garden shed in Falmouth and is almost certainly under recorded in Cornwall so perhaps the survey will shed some light on its distribution.
Another moth, The Hummingbird Hawk-moth, is thought to now overwinter and it would be particularly interesting to receive confirmation of this. It is easily over looked when stationary and for those unfamiliar with it photos can be seen on the highlighted link above.
All sightings of adult moths, butterflies, caterpillars, pupae or eggs during the winter are welcome. If uncertain of identification forward an image and I’ll have a go!
In the last few weeks the Angle Shades caterpillar has been the most common species reported including both brown and green forms.
